A position statement of the American Diabetes Association, with representation by the American College of Osteopathic Family
Physicians, the American Academy of Pediatrics, the American Association of Clinical Endocrinologists, the American Osteopathic
Association, the Centers for Disease Control and Prevention, Children with Diabetes, The Endocrine Society, the International
Society for Pediatric and Adolescent Diabetes, Juvenile Diabetes Research Foundation International, the National Diabetes
Education Program, and the Pediatric Endocrine Society (formerly Lawson Wilkins Pediatric Endocrine Society)

During childhood and adolescence, there is a gradual shift from diabetes care supervised by parents and other adults to self-care
management. The actual change from pediatric to adult health care providers signals a more abrupt change that requires preparation
by patients, their families, and their health care providers. A number of publications from the U.S. and other countries have
highlighted substantial gaps in care during this transition period between pediatric and adult care that often arise in later
adolescence and the subsequent developmental stage of life termed “emerging adulthood.” This is a critical time when patients
not only assume responsibility for their diabetes self-care and interactions with the health care system but when they become
more independent, potentially moving out of their parents’ home to attend college or to join the workforce (1). In the context of these transitions and the developmental issues of this age-group, gaps in diabetes care can result in
suboptimal health care utilization, deteriorating glycemic control, increased occurrence of acute complications, emergence
of chronic complications of diabetes that may go undetected or untreated, and psychosocial, behavioral, and emotional challenges.
With the increasing incidence of both type 1 and type 2 diabetes in childhood, adolescence, and young adulthood, there is
an increase in the absolute numbers of youth with diabetes in this transition period, highlighting the need for a framework
of care and education for this population and a call for additional research in this area.

Substantial challenges relating to the transitional period include the following:

The dearth of empirical evidence on the best approaches to the transition process

Lack of well-defined criteria for determination of transition readiness

The changing social and demographic characteristics of young adults that may influence their utilization of health care

Gaps in health insurance during this transitional period

Differences in learning styles between individuals in this transition period compared with both younger children and adults
beyond the period of emerging adulthood

Deficiencies in training of health care professionals in care delivery for emerging adults with diabetes

Most of the limited evidence base has focused on transitions in care for youth with type 1 diabetes. The recent emergence
of type 2 diabetes in children and teenagers highlights an absolute deficiency of studies on transitioning youth with type
2 diabetes from pediatric to adult care (2). Although some medical and psychosocial issues may be different between these groups of youth with diabetes, many are assumed
to be similar.

In March 2010, the American Diabetes Association (ADA) convened a multidisciplinary group of experts and people with diabetes
(see Appendix for organizations and individuals) to review the issues that confront both youth and young adults with diabetes and health
care professionals during this critical transition process from pediatric to adult care. The issues that need to be considered
to understand the process of transition were described and discussed. This resulting statement provides a framework for health
care delivery during the transition period and an agenda for future research.

RATES OF DIABETES DURING THE TRANSITION YEARS

The SEARCH for Diabetes in Youth study has estimated that about 15,000 youth are diagnosed annually with type 1 diabetes and
about 3,700 are diagnosed annually with type 2 diabetes (3). In 2001, SEARCH estimated that there were approximately 154,000 youth under the age of 20 years with diabetes (3,4), and in 2010 the estimated number of youth with diabetes was 215,000, representing 0.26% of individuals in this age-group
(5).

Worldwide, the prevalence of type 1 diabetes in children and young adults has doubled in the past 25 years and is expected
to double yet again in the next 15–20 years, a phenomenon not observed several decades ago (6,7). The epidemic of childhood obesity has lead to an increased incidence of type 2 diabetes being diagnosed in children and
teenagers (8). Type 2 diabetes remains relatively uncommon in children under age 10 years, with the majority of cases identified in youth
during the 2nd decade of life and affecting predominantly those from racial and/or ethnic minority groups, namely American
Indians, blacks, Hispanics, Asians, and Pacific Islanders (9–13). Furthermore, although the incidence of type 1 diabetes declines toward the middle to the late 2nd decade of life (age 15–19
years) from the peak rates observed during puberty in early adolescence, the incidence of type 2 diabetes continues to increase
with age.

There are limited epidemiological data that span the age range from late adolescence through young adulthood (18–30 years
of age), although there are data that precede and follow this key developmental period. The SEARCH study provides prevalence
estimates for 15- to 19-year-olds in various racial and ethnic populations (9–13). Prevalence of type 1 diabetes for this age-group ranges from 0.43 per 1,000 in Navajo youth to 3.22 per 1,000 in non-Hispanic
whites, while the prevalence of type 2 diabetes ranges from 0.29 (non-Hispanic whites) to 2.36 (Navajo) per 1,000. In a survey
of 11,855 young adults (41% response rate), ages 18–29 years, attending 2-year and 4-year postsecondary educational institutions
in Minnesota, 0.55% of students reported having a diagnosis of type 1 diabetes (E. Ehlinger, personal communication).

The size of the young adult population with diabetes is difficult to know with certainty. The overall numbers of children,
adolescents, and young adults with diabetes in the U.S. in 2007 was estimated at close to a million in a study of diabetes
costs including the age-groups <18 and 18–34 (14). Given the current estimates of the prevalence of diabetes in youth, one can expect that each year there are tens of thousands
of emerging young adults with type 1 or type 2 diabetes who will be transitioning from pediatric to adult care.

EMERGING ADULTHOOD

For the purposes of this statement, we have chosen to focus on the age range of 18–30 years. The preceding period of adolescent
growth and development is a stage of tremendous physical, social, and emotional change that challenges diabetes management
for both youth and health care providers. During this stage of adolescent development, there is a need for ongoing family
involvement in diabetes management in order to reduce the risk of deterioration in glycemic control that often accompanies
adolescence (15).

In contrast to the views of traditional developmental psychology, contemporary thinking is that young adulthood does not immediately
follow adolescence, but begins when youth are in their late 20s or early 30s and that the developmental stage between ages
∼l8 and 30 years defines a period called emerging adulthood (16). Recent cultural trends in America suggest that young people in their 20s delay assuming adult roles with respect to marriage,
parenting, and work compared with young adults in earlier generations. Contemporary developmental theorist J.J. Arnett (16) suggests that the postadolescent period is subdivided into an early phase corresponding to the years immediately after high
school (∼18–24 years) and a later phase when more traditional adult roles are assumed (∼25–30 years). Thinking about the postadolescent
period as consisting of two phases provides a valuable framework when considering diabetes management and may help to ensure
that the clinician's approach and focus are appropriately matched to the emerging adult's life circumstances and readiness
to become an active participant in his/her own diabetes management.

During the early phase of emerging adulthood, the person may be transitioning geographically, economically, and emotionally
away from the parental home. Competing academic, economic, and social priorities often detract from a focused commitment to
chronic disease management. Even as young adults face these competing demands, most do not believe that they have achieved
all of the skills necessary to remain independent and accept these responsibilities on their own (16). Therefore, it may be unrealistic to expect the person with diabetes in the first phase of emerging adulthood to make major
changes in their diabetes management strategies, or even to transition to a new adult diabetes health care provider. Conversely,
for many this early phase is marked by feelings of invulnerability and a tendency to reject adult control, which may further
limit receptiveness to recommendations for diabetes treatment.

During the second phase of the young adult period, the 25- to 30-year-old often has a maturing sense of identity and assumes
adult-like roles in society, such as entering into stable intimate relationships or full-time employment. This phase, when
the individual starts making plans about his/her future life, is often accompanied by a growing recognition of the importance
of striving for better glycemic control and receptiveness to improving self-care behavior. Life partners can be important
supports and agents for change, and a shared sense of investment in the future will often catalyze this change in self-care
behavior. This period, when lifelong patterns of behavior are likely established, can be a critical window of opportunity
for health care interventions.

ISSUES IN THE TRANSITION BETWEEN PEDIATRIC AND ADULT DIABETES CARE

The transition from pediatric to adult diabetes care represents a high-risk period for a person with diabetes, a perfect storm
during which interruption of care is likely for multiple reasons. The young person is leaving what has often been a long-term,
comfortable relationship with health care providers, sometimes without preparation or ready access to a subsequent provider.
There are also multiple psychosocial adjustments during the postadolescent period of emerging adulthood that can be confounded
by financial stressors. Poor glycemic control, the presence of risk factors for complications (hypertension and dyslipidemia),
high-risk behaviors (cigarette smoking and drug and/or alcohol abuse), and emerging complications may further increase the
difficulty of this period. The period of emerging adulthood may be accompanied by uncertainty regarding health insurance coverage
upon completing education or leaving the parental home. Given that individuals in this transition period have had the highest
rates of uninsurance or underinsurance in the past, the reforms of the Patient Protection and Accountable Care Act in the
U.S. should be of particular benefit to emerging adults with chronic conditions such as diabetes.

The following sections elaborate on eight areas of particular relevance for the emerging young adult with diabetes: differences
between pediatric and adult care, poor glycemic control, loss to follow-up care, acute complications, psychosocial issues,
reproductive health issues, substance use and abuse, and chronic complications.

Differences between pediatric and adult care

There are fundamental differences in the approach and delivery of diabetes care between pediatric and adult patients. Diabetes
care for pediatric patients requires involvement of the family in order to be successful. Young children do not have the cognitive
ability to master diabetes management, and teens often do not possess the emotional maturity to sustain the tasks of daily
therapy. Although health care delivery varies by system and access, in the pediatric health care setting, visits tend to be
family-focused, holistic, and centered on management approaches that fit diabetes into the child and family's lifestyle. Diabetes
visits and management approaches include parents/guardians as well as the youth.

In adult care, the focus is more on the autonomously functioning individual patient, who can be informed or counseled but
then is expected to make his/her own choices about behavior or treatments. Adult visits tend to be substantially shorter and
focused on medical problems. Adult patients choose who they do and do not want to have access to their health information
and are largely considered independent consumers of health care. Whereas individuals change gradually from childhood to adulthood,
the change in health care provider can be abrupt and unsettling, suggesting that a more gradual transition may be preferable.

Poor control of glycemia and other risk factors

There remains a considerable gap between the recommended glycemic control levels and the levels actually achieved in clinical
practice, especially for older teens and young adults. The SEARCH for Diabetes in Youth study showed that only 32% of youth
with type 1 diabetes aged 13–18 years and 18% of those aged ≥19 years achieved ADA-recommended A1C targets (17). On the other hand, National Health and Nutrition Examination Survey data reveal that 56% of adults achieve target A1C values
of <7% (18). The greatest proportion of youth with type 1 or type 2 diabetes in poor glycemic control (A1C ≥9.5%) were teenagers; one
of every four patients aged >12 years had such elevated A1C levels (17). Others have documented poor glycemic control during the older teen and young adult years (19,20). Those in the poorest glycemic control are at high risk for both acute complications and chronic microvascular complications
(20,21).

The prevalence of cardiovascular risk factors is much greater in youth with type 2 versus type 1 diabetes, regardless of ethnicity
(22). However, as the general obesity rates among all U.S. children and adolescents increase, youth with type 1 diabetes have
experienced similarly increasing rates and may have additional cardiovascular risk, partly as a result of the suboptimal diets
reported in youth with either type 1 or type 2 diabetes (23). Studies show higher rates of dyslipidemia in obese children and adolescents with type 2 diabetes (22,24,25). Elevated lipid levels in youth with type 1 diabetes appear to be related to level of glycemic control (26). The rates of hypertension in children and adolescents with diabetes compared with those without diabetes are largely related
to overweight or obesity status. Fatty liver disease is also more common among obese children with insulin resistance and
diabetes, may precede the diagnosis of type 2 diabetes, and has also been linked to type 1 diabetes (27). Progression and optimal treatment of fatty liver disease is not known in adolescents, but the disease can progress to cirrhosis
and death. These risk factors need to be addressed in the adolescent and transitioning young adult.

Loss to follow-up

The competing distractions of young adult life often interfere with the requirements of successful diabetes management, including
the need to maintain consistent medical care. Transitioning older teens and young adults are at high risk for disengagement
from health care and, in turn, the emergence of complications that may go undetected without appropriate follow-up diabetes
care and screening. There are adverse short-term (hypoglycemia, hyperglycemia, or diabetic ketoacidosis [DKA]) and long-term
(nephropathy and retinopathy) outcomes when patients with diabetes are lost to follow-up or have infrequent encounters (21,28,29). Rates of hospitalization and emergency use and costs of care are higher when glycemic control is poor (21). Glycemic control and diabetes outcomes are also poorer when patients do not understand or participate in their care.

The relative risk of death is higher for young adults with diabetes than for those without diabetes (30). Lapses in care or loss to follow-up accounts for some of these adverse outcomes of transitioning older teens and young
adults (31–33). Older teens and young adults with diabetes, especially those from racial/ethnic minority or low socioeconomic status backgrounds,
require increased access to care in order to maintain continuity and coordination of multidisciplinary support and to receive
ongoing self-management support. Continuous follow-up helps reduce the need for costly, acute hospitalizations and provides
for early intervention of chronic complications to optimize long-term health outcomes and functioning.

Increased risk for acute complications

A variety of factors may increase the risk of hypoglycemia and severe hyperglycemia or DKA in transitioning youth, including
loss of parental supervision of diabetes care and reduced attendance at diabetes medical visits. The challenges of work and/or
school often take precedence over diabetes care. Other lifestyle changes may include increases in alcohol consumption, changes
in physical activity levels, varying motivation for self-care (as emerging young adults separate from parents), and differing
dietary patterns from a more controlled family-home environment. Although data are lacking on the incidence of severe hypoglycemia
and DKA during the early transition years, in the Diabetes Control and Complications Trial (DCCT) adolescents aged 13–17 years
at study entry and 20–24 years at study's end had a higher rate of severe hypoglycemia than adults (34). Rates of DKA in older adolescents are associated with nonadherence and poorer glycemic control (35).

Recent studies of continuous glucose monitoring (CGM) have assessed rates of overnight hypoglycemia in individuals aged 15–24
years, with nocturnal hypoglycemia documented during 8.8% of nights (36). Real-time CGM and sensor-augmented pumps have the potential to reduce the incidence of hypoglycemic events while improving
A1C in those with type 1 diabetes, although poor adherence regarding consistent CGM usage during the adolescent and young
adult years has been a major limiting factor (37).

Psychosocial issues

Psychosocial challenges are common during emerging adulthood, occur more often in those with diabetes compared with those
without diabetes, and occur more commonly during emerging adulthood than during other stages of life. Living with diabetes
often brings with it a broad range of diabetes-related distresses. Diabetes-specific stressors that occur frequently and interfere
with effective self-care include not having clear and concrete goals for diabetes care; feeling discouraged and overwhelmed
with the diabetes regimen; uncomfortable interactions concerning diabetes with family, friends, or coworkers who do not have
diabetes; feelings of guilt or anxiety about getting off track with diabetes self-care; and worrying about the future and
the possibility of serious complications (38). Anxiety disorders, the most frequently diagnosed psychiatric disorder in the general population, can complicate living
with and self-management of diabetes, for example when fear of injections triggers panic attacks, when symptoms of anxiety
are confused with hypoglycemia, or when anxiety about hypoglycemia becomes unmanageable.

Depression or the presence of depressive symptoms is a well-known comorbid condition for individuals with diabetes. In addition
to being a barrier to effective diabetes self-management, depression is linked to poor glycemic control (39) and diabetes complications (40). In adolescents with diabetes, including 18- to 20-year-olds, 15–33% report depressive symptoms (41,42), while 23–35% of emerging adults (18–28 years of age) with diabetes do so (43). Recent data from the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY) study document similar levels
of depressive symptoms in adolescents with type 2 diabetes, with rates of clinically significant depressive symptoms exceeding
20% in older adolescent females (44). In addition, depressive symptoms were inversely associated with quality of life. Recognizing the trajectories of depressive
symptoms to worsen and impact physical and psychosocial well-being as older teens transition into young adulthood, it is important
to monitor and refer older adolescents and young adults with type 1 or type 2 diabetes to appropriate mental health resources.

Adolescent and postadolescent young women with diabetes have 2.4 times the risk of developing an eating disorder than age-matched
women without diabetes (45). Although disordered eating behaviors occur in both sexes, they are much more common in women than men. About 30% of all
women taking insulin struggle with subclinical symptoms of disordered eating, such as restrictive eating, a preoccupation
with weight and shape, feelings of guilt after eating, and strategic misuse of insulin for weight control (46). Up to 60% are trying to lose weight with unhealthy weight control behaviors (47), with some studies showing as many as 57% of adolescents and young adults involved in the particularly unhealthy weight
control behavior of intentional insulin mismanagement (48–50). One survey of 11,855 Minnesota students attending 2-year and 4-year colleges or universities revealed that about twice
as many students with type 1 diabetes had been diagnosed with anorexia or bulimia compared with students without type 1 diabetes
(overall survey results at http://www.bhs.umn.edu/surveys/index.htm; data on type 1 diabetes not displayed).

Clinically diagnosable eating disorders such as anorexia and bulimia as well as subclinical disordered eating attitudes and
behaviors present a serious health risk to the emerging adult with diabetes. Disordered eating is associated with poor metabolic
control, reduced adherence, depression, increased risk of DKA, and increased rates of microvascular complications in women
with diabetes (20). Severe eating disorders, especially anorexia nervosa and purging through insulin omission, are life threatening, and such
patients may require hospitalization on an inpatient eating disorders unit experienced in taking care of patients with type
1 diabetes. Disordered eating is not exclusive to youth with type 1 diabetes; 6% of a large cohort of adolescents with type
2 diabetes had clinical and 20% had subclinical levels of binge eating behaviors associated with more extreme obesity, global
eating disorders, depressive symptoms, and poorer quality of life (51).

In summary, eating disorders and affective disorders are especially serious in emerging adults who have diabetes because insulin
omission, depression, anxiety, and fear of hypoglycemia interfere with diabetes self-care behavior during a time when these
patients may have fallen between the cracks of the pediatric and adult health care systems. Moreover, longitudinal cohort
studies have revealed that there is a subgroup of adolescents with serious mental health and behavior problems who continue
to deteriorate as they enter their 20s, often with onset of microvascular complications and early mortality. Clinicians who
care for emerging adults with type 1 diabetes need to evaluate the mental as well as the physical health history of their
new patients and foster access to mental health providers for consultation and collaborative care for the diagnosis and treatment
of eating disorders, depression, anxiety, and fear of hypoglycemia. The same principles hold for individuals with type 2 diabetes,
although there are fewer published reports. Because the TODAY study is a longitudinal study of adolescents with type 2 diabetes,
this investigation will provide important data on the onset, progression, and possible resolution of disordered eating behaviors
and depression as these patients enter emerging adulthood (51).

Sexual and reproductive health issues

There is no reason to expect that emerging adults with diabetes will behave differently than their peers with respect to the
potential for unintended pregnancies and acquisition of sexually transmitted infections. Thus, sexual behavior and reproductive
health are important areas for discussion by both pediatric and adult care providers, even when the many medical issues related
to diabetes and its complications tend to take precedence, delegating these issues to a secondary status.

Contraception needs to be addressed with adolescents and young women with diabetes—even more so than in women without diabetes—because
of the need for reproductive planning in order to avoid unplanned pregnancies and maximize the outcomes of diabetic pregnancies.
Contraceptive use to prevent pregnancy is lower among adults with diabetes aged 20–44 years; 39% of those with diabetes were
not current users of contraception compared with 27% of adults without diabetes (52). Among teens aged 13–19 years with diabetes, only 16% reported using birth control and, among those ever sexually active,
67% had ever used birth control (53). An increasing number of young women with preexisting diabetes are becoming pregnant and delivering babies (54). Given that the highest pregnancy and birth rates occur in the 18- to 30-year-old age range, the importance of preconception
counseling and care for individuals with type 1 and type 2 diabetes is clear. Fewer than one in four young women aged 16–20
years with diabetes were aware of maternal and fetal risks of pregnancy and of the need for good glycemic control in order
to conceive and give birth to a healthy child (55). Although preconception care is often not a routine part of ongoing diabetes care, the development of a reproductive health
plan as suggested by the Centers for Disease Control and Prevention Select Panel on Preconception Care is essential (http://www.cdc.gov/mmwr/preview/mmwrhtml/rr5506a1.htm).

Alcohol, smoking, and drug abuse

Emerging adults with diabetes may risk their health by involvement in behaviors such as drinking alcohol and smoking cigarettes.
Among samples of adolescents and emerging adults with diabetes, alcohol and tobacco use seem equivalent to rates in those
without diabetes. Alcohol use worsens glycemic control (56) and is a known risk factor for severe hypoglycemia, while cigarette smoking increases cardiovascular risk and risk for microalbuminuria
among adolescents and emerging adults with diabetes (57,58). Involvement in these and other high-risk behaviors such as drug abuse places these youth at risk for immediate and long-term
diabetes complications. In addition, such high-risk behaviors impinge upon the safety of the older adolescent and young adult
who is beginning to drive. Risks of these behaviors as well as the risks associated with hypoglycemia while driving should
be discussed. Abstinence from alcohol and substance use while driving should be directly discussed, and appropriate blood
glucose monitoring along with prevention and treatment of hypoglycemia before and during driving should be established.

Emergence of signs of chronic diabetes complications

Rates of clinically apparent diabetes complications are low in adolescents, although there is evidence of early microvascular
complications. About 10% of adolescents with type 1 diabetes have microalbuminuria (59), whereas ∼30% of teens with type 2 diabetes have microalbuminuria (27); the SEARCH study has verified a threefold higher rate of microalbuminuria in youth with type 2 compared with those with
type 1 diabetes (60). Higher rates of microalbuminuria and hypertension are seen in youth with type 2 than youth with type 1 diabetes, despite
the fact that those with type 2 diabetes on average have shorter duration of disease (61). Retinopathy is rare among teens with type 1 diabetes, although more common than among teens with type 2 diabetes (61); data are forthcoming from the TODAY study regarding the rates of retinopathy among teens and young adults with type 2 diabetes
to supplement the modest data currently available. When neuropathy testing is performed, ∼20% of adolescents with diabetes
have evidence of peripheral sensory polyneuropathy and/or findings of autonomic neuropathy (61).

The beginnings of atherosclerotic disease occur in children and adolescents (62). Risk factors such as elevated LDL cholesterol level, reduced HDL cholesterol level, smoking, and higher A1C levels were
associated with fatty streaks and raised intimal lesions in autopsy studies. Predictors of abnormal vessels in the Bogalusa
Heart Study included high BMI, high total and LDL cholesterol, elevated triglycerides, and high systolic and diastolic blood
pressure (63). Therefore, risk factors similar to those identified in older individuals impact the development of atherosclerosis in adolescents
and young adults. The presence of diabetes is associated with elevated carotid artery intima-media thickness, stiffer blood
vessels independent of lipids, and higher levels of inflammatory markers compared with nondiabetic individuals (64,65).

Although pediatricians treat diabetes complications infrequently, adult physicians follow guidelines that are specifically
written to address the complications of diabetes. Adult guidelines are often based on data from older adults, usually with
type 2 diabetes; therefore, their application to younger individuals with type 1 diabetes needs to be individualized. Nonetheless,
discussion of diabetes-related complications and preparation of the transitioning older teen or young adult for changes in
care practices should occur prior to transition.

APPROACHES TO IMPROVE TRANSITIONS IN CARE

Previously published approaches on transitioning older teens and emerging adults with diabetes

Teens and young adults require assistance with transition because they are a vulnerable population at risk for loss–to–follow-up
care and poor health outcomes. Once transferred out of pediatric care, published reports provide evidence of gaps in follow-up
care with a decrease in physician visits after transfer (32,33,66). Patients with fragmented follow-up care demonstrated poorer glycemic control and a higher rate of hospitalization (67). Therefore, the goal of transition programs is to focus on easing the transfer process from pediatric to adult care providers.

There is substantial interest in identifying effective ways to transition older teens and young adults with diabetes to adult
care providers. Much of the published literature on the topic describes observational studies or uncontrolled programs, and
there are no published, empirically tested, randomized controlled trials of validated transition programs. Studies using patient
interviews, questionnaire responses, or focus group discussions indicate that young adults describe time as a major challenge
to maintaining contact with the diabetes health care team following transfer. Some reports have suggested evening hours or
flexible clinics. Others have suggested a longer visit as the initial meeting with the adult provider, the provision of special
clinic times that focus exclusively on teens to young adults up to age 30 years, and the need to provide the transitioning
patient with written information regarding the transfer process and the new physician. This information is in addition to
the medical summary of the patient's past diabetes health care that should be provided to the receiving physician. Most of
these studies have substantial limitations because they reflect small sample sizes and particular health care delivery systems
(32,66,68,69). A recently published systematic review of the transition between pediatric and adult care identified only 10 studies across
a spectrum of chronic diseases of childhood that evaluated particular interventions and associated outcomes (70). Of these studies, eight included patients with diabetes, one included patients with cystic fibrosis, and one included organ
transplant recipients. The interventions targeted either the patient through education and skills training, staff through
identification of coordinators or combined pediatric and adult team members, or delivered services through the creation of
separate young adult clinics or enhanced after-hours phone support. While six of the studies reported improvements in either
glycemic control, the occurrence of complications, or rates of follow-up visits and screening procedures, study methodologies
varied, with only two studies using a controlled, comparison group design. Indeed, recent recommendations for the transition
from pediatric to adult care for patients with cystic fibrosis focus on the preparation of the pediatric care providers, the
training and availability of adult care providers versed in cystic fibrosis management, and assessment of transition readiness
of pediatric patients and families rather than on empiric studies (71).

Models of transition care

There are a few published reports of transition care models that have been established in the U.K., Spain, Australia, and
Canada. The U.K. model evaluated different systems varying from transfer to an adult clinic or different hospital, transition
to a combination of pediatric and adult care providers, or transfer to a young adult clinic within the same pediatric hospital
(33). The latter two approaches were associated with greater attendance at follow-up visits than the former. Other programs have
included transition coordinators, sometimes referred to as patient navigators or care ambassadors, and other approaches that
focused on transition education programs. The education programs included workshops aimed at preparing the transitioning teen.
Some programs included monthly visits for the first 3–6 months in efforts to reduce loss to follow-up, while others used the
transition coordinator to schedule and reschedule any missed appointments (31,69). Future efforts need to standardize and empirically evaluate these various approaches with attention to assessing medical
as well as psychosocial outcomes of care (1,72). Additionally, there are settings, such as in family practice, where care can continue uninterrupted throughout the transitioning
period.

Although there are a few observational studies addressing transitioning youth with type 1 diabetes (69,73), there are essentially no studies on transitioning individuals with type 2 diabetes. Given that the number of youth with
type 2 diabetes is increasing, this is an important area of study.

Programs need to be designed and evaluated that identify a transition coordinator (i.e., care ambassador or patient navigator)
who reaches out to the transitioning emerging adult using multiple means (phone, mail, e-mail, text messaging, social media,
etc.) to ensure timely follow-up visits. Another model that needs to be designed and evaluated for older transitioning adolescents
is a special clinic in which both pediatric and adult providers are in attendance.

OTHER ORGANIZATIONS’ RECOMMENDATIONS FOR TRANSITION OF EMERGING ADULTS WITH DIABETES

Many professional organizations have identified the need to provide guidelines to ease the transition from pediatric to adult
care, though not specifically for youth with diabetes (1,74). In 2002, the American Academy of Pediatrics, the American Academy of Family Physicians, and the American College of Physicians–American
Society of Internal Medicine (75) released a policy statement that noted the goal of an effective transition plan is to provide developmentally appropriate
health care services that continue uninterrupted as the individual moves from adolescence to adulthood. Similarly, in 2003,
the Society for Adolescent Health and Medicine (76) published a position statement identifying the importance of organized and coordinated transition programs. These position
statements along with a recent statement from the American Academy of Pediatrics (77) provide guidelines for the design and implementation of successful transition programs based upon published studies and
expert opinion. Similarly, our committee created recommendations based upon published studies, models of transition across
pediatric chronic diseases such as cystic fibrosis, published guidelines regarding the current recommendations for diabetes
care for pediatric and adult patients, and expert opinion.

ADA RECOMMENDATIONS FOR CARE TRANSITION OF EMERGING ADULTS WITH DIABETES

The ADA level-of-evidence grade, as shown in Table 1, is provided in parentheses.

1. Pediatric health care providers, working collaboratively with the patient and family, should prepare the developing teen for
the upcoming transition in health care delivery beginning at least 1 year prior to the transfer to adult health care providers,
and likely during the early adolescent years. (E)

2. Preparation should include a more directed focus on diabetes self-management skills for the teen/emerging adult and his/her
parents. There should be a gradual transfer of diabetes care responsibilities to the teen from the parent or guardian. Broadening
responsibilities go beyond diabetes management tasks such as glucose self-monitoring and insulin administration and should
include scheduling appointments and ensuring a proper supply of medications and supplies. Diabetes education should be redirected
to the growing and developing teen rather than focused exclusively on the parents. (E)

3. Preparation should include information about the differences between pediatric and adult providers in their approaches to
care, as well as education regarding health insurance options and how to maintain coverage. (E)

4. The pediatric provider should prepare and provide to both the patient and future adult care provider a written summary that
includes an active problem list, compilation of medications, assessment of diabetes self-care skills, summary of past glycemic
control and diabetes related comorbidities, as well as a summary of any mental health problems and referrals during pediatric
care. (E)

The National Diabetes Education Program, a joint program of the Centers for Disease Control and Prevention and the National
Institutes of Health, has developed a template that can be helpful (http://ndep.nih.gov/transitions/).

5. Health care providers need to recognize the vulnerability of emerging adults with diabetes to loss of consistent health care
and difficulties in adhering to diabetes management due to competing psychosocial, educational, and vocational changes, leading
to deteriorating glycemic control. Both pediatric and adult care providers should assist in providing support and links to
resources that could benefit the patient. (B)

6. The transferring health care providers should provide emerging adults with specific referrals to adult care providers versed
in the principles of intensive diabetes management to match the particular needs of the patients with type 1 or type 2 diabetes.
One might consider creation of a directory of adult providers with expertise and interest in the care of young adults. (E)

7. The transferring providers should empower the emerging adults with links to resources that can help them reconnect to care
should they become lost to follow-up. Consideration should be given to assisting the young adult with scheduling the first
appointment with the adult care provider within 3–4 months of the final pediatric visit; a care ambassador or patient navigator
can aid the transitioning young adult with follow-up to ensure timely visits. (C)

8. Care must be individualized and developmentally appropriate, with an emphasis on adherence to diabetes self-management and
consistent use of glucose-lowering medications in order to prevent acute and long-term complications of diabetes. (B)

9. Emerging adults with diabetes should be evaluated and treated for disordered eating behaviors and affective disorders. It
is important for the diabetes provider to have a mental health referral source who understands the fundamentals of working
with individuals with diabetes. (C)

10. Ongoing visits should occur every 3 months for patients taking insulin and every 3–6 months for patients with type 2 diabetes
not taking insulin, according to current ADA recommendations. (E)

11. Screening guidelines for microvascular and macrovascular complications in pediatric and adult patients with diabetes should
be followed. (B)

12. Assessment of risk for macrovascular complications should begin in childhood according to guidelines for lipid screening,
blood pressure assessment, and weight management. Management of lipids and hypertension should proceed according to pediatric
and adult guidelines. (B)

13. Birth control, pregnancy planning and risks, prevention of sexually transmitted illnesses, use of alcohol and drugs, smoking,
and driving should be discussed with the older teens and the emerging adults by both pediatric and adult providers with an
emphasis on the interplay of these issues with diabetes. (E)

SUMMARY AND IMPLICATIONS

For emerging young adults with diabetes, it is particularly important to create effective and translatable processes for the
transition in care from pediatric to adult providers in order to optimize well-being and health for the near term. It is additionally
imperative for these young adults to achieve target glycemic control in order to prevent long-term complications and to maximize
lifelong functioning. There are no proven strategies to achieve these goals, although programs that particularly target the
young adult with diabetes through education, skills training, specialty transition clinics, or addition of transition coordinators
appear to offer promise. Our current knowledge regarding this transition process calls for ongoing and expanding research
initiatives, including the continued training and identification of adult providers versed not only in the medical care but
also in the psychosocial needs of the young adult with diabetes. The next decade should see the emergence of evidence-based
strategies that support best practice for the growing numbers of young adults with type 1 and type 2 diabetes who will be
making this important transition.
